MANUFACTURE OF WHITE LEAD.

SPECIFICATION forming partof Letters Patent No. 374,716, dated December 13, 1887. Application filed July 13, 1887. Serial Ito/244,196. (No model.)

To all whom; it may concern.-

Be it known that I, WILLIAM P. TALBOT, of

' Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in the Art of Making White Lead, of which the following is aspecification.

The object of my improvement is to provide means for spacing thelead buckles,when piled up in the corroding-pots in the well-known process of making white lead, by asimpler and more acceptable method than has been heretofore employed.

I will first describe in detail apractical mode of carrying my improvement into effect, and then point out the various featuresof the improvement in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarletters of reference designate corresponding parts in all the figures.

Figure 1 is a vertical section of a corrodingpot, and contains a pile of buckles, illustrating the application of my improvement. Fig. 2 is an enlarged inverted plan view of a lead buckle constructed in accordance with my improvement. of the said buckle on the lines as x and y y, respectivel y.

Figs. 3 and 4 are crosssections 'corroding-vapor to every portion thereof.

The ribs are, owing to their blade-likeform, quickly corroded with the body of the buckle, and thus serve to increase the amount of white lead obtained from each buckle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.

As an improved article of manufacture, a circular lead buckle cast on one face. with blade-like ridges arranged on opposite sides of a diameter of the buckle, but considerably distant from its periphery, as and for the purpose specified.

WILLIAM P. TALBOT.
